Starburst Galaxy M82: radio view 20/09/1999
The radio image shows a region about 3000 by 2000 light year across. It was made by combining data from the United Kingdom's MERLIN (Multi--Element Radio--linked Radio Interferometer) with data from the Very Large Array (VLA) in New Mexico.

The radio image shows a region about 3000 by 2000 light year across. It was made by combining data from the United Kingdom's MERLIN (Multi--Element Radio--linked Radio Interferometer) with data from the Very Large Array (VLA) in New Mexico. The small bright patches are the remnants of supernovae that have occurred in the last thousand years, and the large diffuse patches are thought to be caused by the accumulation of thousands of supernovae.

Chandra's precise x-ray images of this starburst wind, together with optical, infrared and radio images, will enable astronomers to study all the components of a starburst, from the formation of stars to the explosion of matter out of the galaxy.
